Purpose
To evaluate the clinical performance of a new isofocal monofocal advanced intraocular lens bilaterally implanted. The primary end point was to assess uncorrected and corrected visual acuity at far, intermediate, and near distances. The secondary objective was to analyze binocular defocus curves.
Setting
Institut ophtalmologic de l'Ouest in the city of Nantes France
Methods
This was a retrospective observational study including patients who underwent cataract surgery with bilateral implantation of the a new Monofocal advanced IOL with isofocal optical design; all surgeries were performed by the same experienced surgeon. At three months postoperatively, the following parameters were measured: manifest refraction, monocular and binocular Uncorrected and Corrected Distance Visual Acuity (UDVA, CDVA), Uncorrected and Distance-Corrected Intermediate Visual Acuity (UIVA, DCIVA), Uncorrected and Distance-Corrected Near Visual Acuity (UNVA, DCNVA), and binocular defocus curves.
Results
A total of 42 eyes from 21 patients (mean age: 74.8 ± 6.6 years) were evaluated. At three months postoperatively, mean monocular UDVA and CDVA were 0.14 ± 0.22 LogMAR and 0.04 ± 0.19 LogMAR, respectively.
Mean UIVA and CDIVA were 0.28 ± 0.24 LogMAR and 0.22 ± 0.13 LogMAR, respectively, while UNVA was 0.48 ± 0.18 LogMAR.
Binocular UDVA was 0.1 LogMAR or better in 94.7% of patients, while binocular UIVA at 66 cm was 0.1 LogMAR or better in 62.5% of patients.
The binocular defocus curve demonstrated peak visual acuity values of -0.05 ± 0.01 LogMAR (far distance), 0.14 ± 0.01 LogMAR (intermediate distance), and 0.39 ± 0.02 LogMAR (near distance). Visual acuity of 20/25 or better was maintained over an extended depth of focus of approximately 1.5D.
Conclusions
The new Monofocal advanced IOL with isofocal design provides excellent refractive and visual outcomes for both distance and intermediate vision, demonstrating an extended depth of focus of approximately 1.5D. These results highlight the potential benefits of this IOL in providing enhanced intermediate vision without compromising distance vision. Further large-scale studies are required to confirm these findings.
